I would expect recursion is no problem for games because games
tend to need dynamic binding, which classes provide,
and recursion via class type abstraction works fine
across module boundaries.
The big problem with classes is *intramodule* type recursion,
since mutually recursive class types can't also
recurse with variants and tuples (at least they couldn't
last time I played with them). To fix this you have to
make your class polymorphic, and then instantiate
in an ordinary (recursive) type declaration.
Polymorphic variants may help with this since they
don't need to be declared.
